Community Update 92


  • Release
    • Node version 0.9.15 is being released later today RNode-0.9.15 release plan
    • The 0.9.15 includes the new type safe API (instead of Either), Fixes for Long Proposal Times Issue, Offchain-data API (events API) improvements and other incremental progress in features discussed below.

  • Sprint 38 in progress
    • Main focus on (a) long proposal times (b) cost accounting (d) Casper tests independent of network layer (e) Type Safe API instead of Either (f) completing peek merge functionality (g) API to replace ListenForData@name (off-chain observability of deploy results) (h) Planning and implementation for Network safety, reliability and hardening
    • Ongoing implementation of hardening.
    • Launch readiness planning is ongoing
    • Cost accounting - implementation ongoing. 
    • Progress in long propose times: multiple streams of implementation and investigation:
      • Completed- Synchrony constraints implemented as a tunable parameter.
      • Completed- A second part of the solution is being implemented to promote efficient use of the network by sending block hashes instead of whole blocks to all the nodes. Details in RCHAIN-3819 Getting issue details... STATUS  
      • Completed-Additional Network layer improvements being implemented - Casper waiting on full outgoing message queue, eliminate delays and retries in block streaming, optimal sizes for incoming and outgoing message queues  RCHAIN-3858 Getting issue details... STATUS
      • Completed - Implemented improvements in Estimator performance - Investigation of Estimator performance as a source of erratic behaviour
      • Exploring fairness constraints as an additional mechanism to address long proposal times.
      • We continue to explore various test parameters and more complex contracts, to both test the stability of this issue and make it manifest sooner if it exists.
    • In Progress - In RSpace, an API is implemented for DAG discovery and block discovery, to enable an alternative to ListenForData@Name (Off-chain observability of deploy results). Relevant tickets are  RCHAIN-3760 Getting issue details... STATUS   RCHAIN-3661 Getting issue details... STATUS  and   RCHAIN-3762 Getting issue details... STATUS  and  RCHAIN-3812 Getting issue details... STATUS  
    • Ongoing - The changes are now being tested in development as well as in use cases like Rcat. Necessary changes to Rcat being made to use the new API, so it can be tested.
    • Ongoing - In Casper, ongoing work on pre-requisites for non-game-able source of randomness for the validator to use, to pick a new validator from the 'bonding draw set'  RCHAIN-3195 Getting issue details... STATUS
    • In Review - Implementation of mult-sig vault features is ongoing as detailed in  RCHAIN-3392 Getting issue details... STATUS   RCHAIN-3196 Getting issue details... STATUS   RCHAIN-3223 Getting issue details... STATUS  and  RCHAIN-3773 Getting issue details... STATUS .  Next step is to write tests for this.
    • Completed - New API has been implemented with type safety, responding to community requests. and    RCHAIN-3839 Getting issue details... STATUS  
    • Refactoring, Optimizations and bug fixes - ongoing 
    • Exploring technical options and planning for Rhoc to Rev conversion, wallets and third party readiness - ongoing. Providing them documentation and support in node setup and testing, 
    • Getting ready to focus on documentation.
